This thesis aims to analyze the construction of gender in the development discourse expressed in a program conducted by the German development agency GIZ in Morocco. The analysis of about ten interviews with project managers and participants revealed the way they construct gender. Within the development discourse, gender is constructed by various actors (development agencies, local political institutions, feminist associations, etc.), with capacities for appropriation and adaptation. This places the construction of gender at the intersection between the international and the local, the North and the South, the universal and the specific. The development discourse tends sometimes to normalize gender as a measurable, pragmatic, performance- and result-oriented concept, instead of making it a political issue. On the other hand, gender is constructed by simplified ideas and representations of social relations between men and women in the Third World and in the East, taking the West as a referent. By adopting a feminist and postcolonial theoretical framework, this thesis pays particular attention to power relations, representations and discourses, and opposes itself to essentialism.
